Visual representation of the conceptual model to facilitate planning of dietary intervention at household level. The visual representation of the conceptual model is composed of five parts: the central three-stage spiral representing the three stages-of-change; the ‘impact factors’ along the stem of the spiral; the ‘change processes’ on the right that enable progress from one stage to the other; the background factors on the left that act at all stages; and the overarching influence represented by a transverse plane between the first two stages.
